SparkPost Go API client

The official Go package for using the SparkPost API.

Installation

Install from GitHub using go get:

$ go get github.com/SparkPost/gosparkpost

Get a key

Go to API & SMTP in the SparkPost app and create an API key. We recommend using the SPARKPOST_API_KEY environment variable. The example code below shows how to set this up.

Send a message

Here at SparkPost, our "send some messages" api is called the transmissions API - let's use it to send a friendly test message:

package main

import (
  "log"
  "os"

  sp "github.com/SparkPost/gosparkpost"
)

func main() {
  // Get our API key from the environment; configure.
  apiKey := os.Getenv("SPARKPOST_API_KEY")
  cfg := &sp.Config{
    BaseUrl:    "https://api.sparkpost.com",
    ApiKey:     apiKey,
    ApiVersion: 1,
  }
  var client sp.Client
  err := client.Init(cfg)
  if err != nil {
    log.Fatalf("SparkPost client init failed: %s\n", err)
  }

  // Create a Transmission using an inline Recipient List
  // and inline email Content.
  tx := &sp.Transmission{
    Recipients: []string{"[email protected]"},
    Content: sp.Content{
      HTML:    "<p>Hello world</p>",
      From:    "[email protected]",
      Subject: "Hello from gosparkpost",
    },
  }
  id, _, err := client.Send(tx)
  if err != nil {
    log.Fatal(err)
  }

  // The second value returned from Send
  // has more info about the HTTP response, in case
  // you'd like to see more than the Transmission id.
  log.Printf("Transmission sent with id [%s]\n", id)
}
